What range of MHz to expect from commonly available VVCs
My own (as in yet another) calculator for small-loop transmitting antennas functions differently from all others. Hopefully in a way you will find handy. Focus is chiefly on tuning capacitor. Because once you have either rolled, brazed, or soldered the main loop into a unit whole, there’s no easy way to change that. Also, the loop you can make however you want. Your choices of tuning capacitor, though, can be very limited. Especially if you’re wanting to use a VVC.
Thus I present for your kind consideration my own contestant in an already well-packed arena. Two things it does better than most. Firstly that, for running in a continuous loop, there is no tiresome Calculate button to continually re-click. Secondly is that I have the highest personal confidence in its predictions for loop LÂ (ÎĽH) and Cs (pF). This because of employing ultra-modern algorithms recently authored by Robert (Bob) Weaver and David Knight, G3YNH.

What's in a name? I too was confused for a long time. But one is a sub-set of the other. And my calculator does both.
The designation magnetic loop specifies a main-loop circumference necessarily smaller than 0.05 λ, according to some. And by no means larger than 0.1 λ, according to many. Only when thus configured does the antenna enjoy deep side nulls.
Larger sizes still work very well. Better, even, if it's radiation efficiency you value most. The self same antenna, when tuned for higher frequencies, gradually loses its side-nulls while gaining higher efficiency. And therein lies a critical difference. Down low it's a magloop; up high it's only a small loop. The same basic antenna structure, but with two very different behaviors.
And magloops came first, their deep nulls important for use in direction finding. You see them in movies about WW2: atop Nazi trucks roaming through streets in search of French resistance cells; mounted on bombers following a radio beacon aimed out of England toward Dresden Germany to direct night-time fire-bombing raids. There is history in the special distinction.
And so, after having twice now suffered (and rightly so) polite harrangues from others much better in-the-know, I bow to the nomenclature gurus, re-naming my program for what truely it is: a calculator for small loop antennas (among which over-category magnetic loops are a particularly venerable sub-set).
The distinction becomes immensely important as circumference approaches λ/4 and larger. Because now it is hardly even a small loop, but increasingly something closer to curled-up dipole with mutually coupled capacitance hats. And still it will resonate. The radiation pattern, however, will by now be growing a lobe. So that unless it's our goal to shine a warming radiation upon worms or birds, then our capacitor will best be mounted at either three or nine o'clock instead of the usual six or twelve.
You’ll need two things for it to run: my *.exe application itself, plus also the interpreter program on which it runs. Kind of like Java that way, except that the Java interpreter is probably pre-installed on your system. The LabVIEW run-time engine will not be.

Otherwise, Windows will issue dire warnings of an unrecognized app. Once extracted from out of its ZIP archive, however, Windows will know to pass it off to the LabVIEW Run-Time Engine instead.The Red Artist added dozens of looping visual loops, including 18 repeatable daily activity sequences and over 20 highly branching narrative sequences. 🗺️ Future Roadmap: What’s Next Beyond v0.40?
The term "Prison v040" implies a specific version (v040) of a digital model or scene named "Prison." This could be a 3D model of a prison environment, complete with detailed architecture, furnishings, and possibly character models. The "v040" suggests that this is a specific iteration in a series of updates or revisions of the model, with "v040" potentially indicating the version number.
The user interface features a complete visual redesign. Stat displays and sidebars have been reformatted with a raw, institutional aesthetic that mirrors the bleakness of a maximum-security penitentiary.
The landscape of indie narrative-driven games is constantly evolving, and The Red Artist has once again pushed the boundaries with the latest release of their flagship project, . As of late 2025 and moving into 2026, the Prison V.040C2 update has solidified its position as a complex, story-rich experience that dives deep into themes of power, transformation, and psychological maneuvering within a secure facility . prison v040 by the red artist full
New, detailed, "spicy" scenes are now available in the Blackgang kitchen area.
: A brand-new animated sidebar title replaces the old static layout, and 9 semi-animated emojis have been integrated into the text to emphasize shifting tones.
Nine new semi-animated emojis (👿🍑🔓🔥✨) were added to enhance visual feedback during gameplay. B. New Content and Scenes The Red Artist added dozens of looping visual
It could be utilized in the production of animations or movies that require prison scenes.
: The update integrates over 77 new animated GIFs and 18 highly branchable, repeatable scenes. Furthermore, it features 9 new animated character portraits, including the first NPC-to-NPC narrative portrait interaction in the history of the game.
In previous versions, financial interactions heavily penalized the player's schedule. In v040, no longer advances the in-game clock. This allows players to manage their debts or trade underground items without burning precious daylight. Additionally, replication bugs affecting the Latino faction's early-morning cafeteria shifts have been fully patched. 3. Visual and Aesthetic Overhauls The "v040" suggests that this is a specific
The game is frequently updated, with the creator focusing on community feedback and expanding the game's depth in every iteration. 2. Key Features of the Prison v040 Update
The scenes continue to explore the complex, mature relationships within the prison, adhering to the themes established in earlier versions. Why "Prison" V040 Matters (Development Perspective)

Especially not when it comes to the GUI. Even the math itself is largely beyond my poor understanding. Such are my faults. In LabVIEW however, I am fairly comfortable. Thirteen years now, I have put LabVIEW to use in regular support of my job as a test engineer. So I find myself well able to at the very least faithfully instantiate example equations authored by others. So I here tip my hat to the three maestros cited above (my Aussie bush hat to Owen Duffy).
